Chapter 3. Data analysis and sampling
Abstract
This chapter addresses the construct of second-language (L2) proficiency as it pertains to L2 data analysis. In L2 studies, a common practice is to group participants into proficiency categories (i.e., groups such as ‘intermediate’ or ‘advanced’; a practice known as dichotomization). Nevertheless, I argue that, for theoretical and empirical reasons, proficiency should be analyzed as a true continuous variable. Theoretically, we conceptualize adult L2 acquisition as a continuous process driven by basic learning mechanisms that may be constrained by underlying principles. Empirically, I present evidence illustrating how creating categorical groups by carving up a continuous dependent measure is statistically inappropriate. Finally, I address the importance of sampling practices and why it is preferable to include participants from a broad proficiency spectrum.
